Methods of soil analysis.

TL;DR: The results indicated that the ability to in vitro solubilize P is not necessarily associated to the promotion of plant growth.

TL;DR: In this paper, degraded red soil was amended with three different rates (0.5, 1.0 and 2%) of oak wood biochar (W 0.5, W 1.5 and B 0.0 ), with control as 0%.

TL;DR: In this paper, the vertical and lateral variation of soil salinity (measured as electrical conductivity in saturation paste, ECe) using a combination of regression tree analysis and equal-area smoothing splines in a 72,000-ha area located in central Iran was modelled.

TL;DR: A physically-based soil moisture retrieval model in the solar domain (350-2500nm) that is based on the Kubelka-Munk two-flux radiative transfer theory is presented in this article.

TL;DR: In this paper, the authors present a modeling approach aimed at seasonal resolution of global climatic and edaphic controls on patterns of terrestrial ecosystem production and soil microbial respiration using satellite imagery (Advanced Very High Resolution Radiometer and International Satellite Cloud Climatology Project solar radiation), along with historical climate (monthly temperature and precipitation) and soil attributes (texture, C and N contents) from global (1°) data sets as model inputs.

TL;DR: In this paper, the Century ecosystem model was applied to a series of forest and grassland sites distributed globally to examine large-scale controls over soil carbon, including soil texture and foliar lignin content.

TL;DR: In this article, the Rothamsted model is used to calculate the amount of CO2 that would be released from the world stock of soil organic matter if temperatures increase as predicted, the annual return of plant debris to the soil being held constant.

TL;DR: In this paper, the formation of soil structure involves the physical forces of shrinking and swelling created by changes in water status of soils, freezing and thawing, tillage, or by movement of the larger biota in soils.
